<Description of the first elevator>

The first elevator 720 lifts the gripper 710. As shown in the excerpt of Fig. 12, the first elevator 720 includes a first lifting frame 721, two first lifting rails 722, a first driving motor 723, a first power transmitter 724, and the like. Includes.

The first lifting frame 721 is coupled to the first lifting rail 722 to enable lifting. The first lifting frame 721 may be divided into a first lifting part 721a and a first conversion part 721b. Of course, the first lifting portion 721a and the first conversion portion 721b are formed integrally or provided to be integrally coupled.

The first elevating portion 721a is a portion coupled to the first elevating rail 722 so as to be elevating, and a gripper 710 is coupled to the lower end of the first elevating portion 721a.

The first conversion part 721b has a first conversion hole TH1 for converting the rotational force coming from the first power transmitter 724 into a lifting force. Here, a female thread is formed on the inner surface of the first conversion hole TH1.

The first lifting rail 722 is coupled to both front and rear plates forming the support frame 760 and guides the lifting of the first lifting frame 721.

The first driving motor 723 is fixedly coupled to the support frame 760, and generates a driving force required for lifting the first lifting frame 721. The first drive motor 723 has a first drive pulley 723a that rotates according to the operation.

The first power transmitter 724 transmits the driving force generated from the first driving motor 723 to the first lifting frame 721. To this end, the first power transmission 724 includes a first driven pulley 724a, a first driving belt 724b, and a first transmission shaft 724c.

The first driven pulley 724a rotates in conjunction with the rotation of the first driving pulley 723a.

The first driving belt 724b rotates the first driving pulley 723a and the first driven pulley 723a as rotation return points, thereby interlocking the first driven pulley 724a with the rotation of the first driving pulley 723a. .

The first transmission shaft 724c rotates in conjunction with the rotation of the first driven pulley 724a. The first transmission shaft 724c is installed to pass through the first conversion hole TH1, and the upper and lower portions are rotatably coupled to the support frame 760 by the bearing device BA. A male thread is formed in the portion of the first transmission shaft 724c that passes through the first conversion hole TH1, and is screwed with the female thread of the first conversion hole TH1.

Therefore, when the first driving motor 723 operates and the first driving pulley 723a rotates, the first driven pulley 724a and the first transmission shaft 724c are interlocked with the rotation of the first driving pulley 723a. It rotates, and the first lifting frame 721 moves up and down according to the rotation of the first transmission shaft 724c. And, according to the lifting of the first lifting frame 721, the gripper 710 coupled to the first lifting frame 721 rises and descends. Of course, according to the lifting of the gripper 710, the loading tray LT gripped by the gripper 710 is also raised and lowered.

<Description of the pressurizer>

When the electronic component (ED) and the test socket (SK) are electrically connected to the electronic component (ED) loaded in the loading tray (LT) according to the descending of the gripper (710), the electronic component ( ED) is pressed so that the electronic component (ED) is electrically connected to the test socket (SK). As shown in Fig. 13, 16 pressurizers 730 are provided equal to the number of electronic components (ED) loaded in the loading tray (LT), respectively, a pressurizing member 731, a positive pressure cylinder 732, and a connecting member ( 733) and a coupling member 734.

The pressing member 731 presses the electronic component ED downward while descending according to the operation of the second elevator 740 to electrically connect the electronic component ED to the test socket SK.

The positive pressure cylinder 732 supports the pressing member 731 with a positive pressure so that the pressing member 731 can advance and retreat in the vertical direction. To this end, the positive pressure cylinder 732 maintains a positive pressure state by a positive pressure regulator (not shown) provided separately from the connection device 700.

The connecting member 733 connects the pressing member 731 to the cylinder rod of the positive pressure cylinder 732 so that the pressing member 731 can be supported by the positive pressure cylinder 732 with positive pressure.

The coupling member 734 couples the positive pressure cylinder 732 to a second lifting frame to be described later. For reference, as shown in FIG. 14, the pressing member 731 is coupled to the coupling member 734 so as to be elevated by a vertical rail PR and a rail block RB.

The pressurizer 730 as described above descends together when the gripper 710 descends in order to electrically connect the electronic component ED to the test socket SK. Therefore, even if interference resistance occurs while the loading tray LT gripped by the gripper 710 descends, the electronic component ED loaded in the loading tray LT contacts the test socket SK, as shown in FIG. Likewise, since the pressurizer 730 presses the electronic component ED in a downward direction toward the test socket SK, the electronic component ED can be properly connected to the test socket SK.

The positive pressure support of the pressure member 731 by the positive pressure cylinder 732 in the pressurizer 730 as described above has two functions. The first is a function to check whether the electrical connection between the electronic component (ED) and the test socket (SK) is appropriate, as described later, and the second is a function to prevent damage to the electronic component (ED) due to excessive pressing force. .

On the other hand, the pressurizer 730 also functions as a separation preventing device that prevents the separation of the electronic component (ED) loaded in the loading tray (LT). For example, when the loading tray (LT) is elevated or horizontally moved, the lower end of the pressurizing member (731) is positioned while maintaining a minute distance from the electronic component (ED) loaded in the loading tray (LT) as shown in FIG. Because of this, it is to prevent the electronic component (ED) from being out of the correct position. In addition, from the point of view of the function of preventing the separation of the electronic component (ED), the pressurizer 730 is also a shock that occurs when the electronic component (ED) and the test socket (SK) are electrically connected or disconnected. It may be considered to perform a function of preventing the electronic component ED from leaving its original position.

<Description of the second elevator>

The second elevator 740 lifts the 16 pressurizers 730 together. To this end, the second elevator 740 includes a second lifting frame 741, four second lifting rails 742, a second driving motor 743, a second power transmitter 744, and the like, as shown in FIG. Includes.

The second lifting frame 741 may be divided into a second lifting part 741a and a second conversion part 741b. Of course, the second lifting part 741a and the second conversion part 741b may be integrally formed or provided to be combined.

The second lifting part 741a is a part to which the second lifting rail 742 is fixed. And, as shown in Fig. 17, the positive pressure cylinder 732 of the pressurizer 730 is fixed by the coupling member 734 under the second lifting part 741a.

The second conversion part 741b has a second conversion hole TH2 (refer to the withdrawal part) for converting the rotational force coming from the second power transmitter 744 into a lifting force. Here, a female thread is formed on the inner surface of the second conversion hole TH2. In addition, the second conversion portion 741b also serves to couple the second lifting portions 741a spaced apart from each other in the front-rear direction.

The four second lifting rails 742 are fixed to the second lifting part 741a of the second lifting frame 741, and are coupled to the rail block RB fixed to the support frame 760 so as to be able to move up and down. . That is, the rail block (RB) fixed to the support frame 760 does not move in the vertical direction, and has a combined structure in which the four second lifting rails 742 rise and fall.

The second driving motor 743 is fixedly coupled to the mounting plate 761 of the support frame 760, and generates a driving force required for lifting the second lifting frame 741. This second drive motor 743 has a second drive pulley (743a) that rotates according to the operation.

The second power transmitter 744 transmits the driving force generated from the second driving motor 743 to the second lifting frame 741. To this end, the second power transmission 744 includes a second driven pulley 744a, a second driving belt 744b, and a second transmission shaft 744c (refer to a lead-out part).

The second driven pulley 744a rotates in conjunction with the rotation of the second driving pulley 743a.

The second driving belt 744b rotates the second driving pulley 743a and the second driven pulley 744a as rotation return points, thereby interlocking the second driven pulley 744a with the rotation of the second driving pulley 743a. .

The second transmission shaft 744c rotates in conjunction with the rotation of the second driven pulley 744a. The second transmission shaft 744c is installed so as to pass through the second conversion hole TH1, and the upper and lower portions are rotatably coupled to the mounting plate 761 by the bearing device BA. A portion of the second transmission shaft 744c passing through the second conversion hole TH2 is formed with a male thread and is screwed with the female thread of the second conversion hole TH2.

Therefore, when the second driving motor 743 operates and the second driving pulley 743a rotates, the second driven pulley 744a and the second transmission shaft 744c are interlocked with the rotation of the second driving pulley 743a. It rotates, and the second lifting frame 741 is raised and lowered according to the rotation of the second transmission shaft 744c. In addition, 16 pressurizers 730 coupled to the second lifting frame 741 rise and fall according to the lifting of the second lifting frame 741.

<Description of the checker>

When the electronic component (ED) and the test socket (SK) loaded in the loading tray (LT) are electrically connected according to the lowering of the gripper (710), the electronic component (ED) and the test socket ( Check the electrical connection between SK). As shown in FIG. 18, the checker 750 includes a check element 751 fixed to the positive pressure cylinder 732 of the pressurizer 730 and a check-in element 752 fixed to the pressurization member 731 of the pressurizer 730. Includes.

As shown in FIG. 19, the confirmation element 751 detects and confirms the element to be checked 752 through light emission and light reception (refer to arrow A). In this embodiment, when the confirmation element 751 detects the element to be checked 752, the electronic component ED and the test socket SK are not properly connected, and the confirmation element 751 is When the element to be checked 752 is not detected, the electronic component ED and the test socket SK are properly connected.

For example, if the terminal portion of the electronic component (ED) loaded in the loading tray (LT) is not properly inserted into the slot of the test socket (SK) as shown in (a) of FIG. 20, the electronic component (ED) The pressing member 731 is subjected to a pressing force relatively upward. Accordingly, the pressure member 731 is in a state of relatively rising with respect to the descending static pressure cylinder 732 while the descending is stopped despite the descending of the static pressure cylinder 732. In this case, the element to be checked 752 fixed to the pressing member 731 also rises relative to the confirmation element 751 fixed to the positive pressure cylinder 732. Accordingly, the confirmation element 751 detects the element to be checked, and through this, it can be seen that the connection between the electronic component ED and the test socket SK has not been properly made. Of course, if the connection between the electronic component ED and the test socket SK is properly made as in (b) of FIG. 20, the confirmation element 751 cannot detect the element to be checked 752.

Meanwhile, FIG. 21 is a conceptual left side view for generally grasping the arrangement structure of each of the components constituting the connection device 700 as described above. That is, the first elevating frame 721 is coupled to be elevating to the outside of the support frame 760, and the second elevating frame 741 is coupled to be elevating to the inside of the support frame 760. And as described above, the gripper 710 is coupled to the first elevating frame 721 to elevate and descend together with the first elevating frame 721, and the pressurizer 730 is coupled to the second elevating frame 741 to provide a second It goes up and down together with the lifting frame 741. Of course, since the checker 750 is coupled to the pressurizer 730, the second lifting frame 741 is lifted and lowered together.

<Description of the overall operation of the connecting device>

When the loading tray LT in which the electronic component ED is loaded is located in the loading position IP, the connection device 700 moves to the loading position IP and grips the loading tray LT. That is, the first elevator 720 operates so that the gripper 710 descends, and the driving source 712 operates so that the gripper 710 grips the loading tray LT. In addition, the first elevator 720 operates to raise the gripper 710. At this time, the gripper 710 has only a minute gap between the upper end of the electronic component ED and the lower end of the pressing member 731, so that the electronic component ED loaded in the loading tray LT is It is raised to such an extent that it can be prevented from being separated from the original position. Of course, when the standard of the electronic component ED to be tested is changed, the lifting height of the gripper 710 may be set according to the changed standard of the electronic component ED.

When the gripper 710 is raised, the connecting device 700 is moved to the test position TP by the horizontal rail HR and the belt device BA. Of course, the socket board SB of the tester is located under the test position TP. Therefore, when the connection device 700 is moved to the test position TP, the first elevator 720 and the second elevator 740 are operated so that the gripper 710 and the pressurizer 730 descend.

As the loading tray LT descends by the lowering of the gripper 710, the loading tray LT and the socket board SB are matched by the interaction of the matching hole LH and the matching pin LP. Subsequently, the position of the electronic component (ED) is aligned by the interaction of the guide holes (GH ₁ , GH ₂ ) and alignment pins (AP ₁ , AP _{2 ).} It is inserted into the slot. And accordingly, the electronic component ED and the test socket SK are electrically connected.

At this time, whether or not an appropriate connection between the electronic component ED and the test socket SK is connected is confirmed by the checker 750.
